Question

When **adding** two **8 bit** binary
numbers, which of the following statements is true?

Select one:

a. All bits are shifted to the **right** by one
place, giving a **7 bit** number

b. The result might require **16 bits** to
store

c. The result will require the same bits as the larger number

d. The result might require **9 bits** to store

e. The result will also be a **8** number

Answer #1

A). Convert following decimal integers to 8-bit two's complement
binary numbers using any
method . Explain why, If decimal number cannot be represented
with 8 bits.
a. -46 b. -63 c. 118 d. -128 e. 128
B). Perform following operations by converting the decimal
numbers to 8-bit two’s complement
binary. Check results by converting final result to decimal
a. 94-53 b. 15–84

Adder
Start out by picking 2 positive six bit binary numbers that are
less than 3210, written in 2's complement notation. The
eventual goal is to add these two numbers.
1) Look at the LSB bit of the numbers, and using logic gates
(NANDs, NORs, etc.) design a circuit that correctly gives the right
output for any possible combination of bits in the LSB place.
2) Now look at the next column to the left (next to LSB). In
this...
